PACKING.

To all whom it may concern:

Be it known that I, CHARLES I. E. Masrm, a citizen of the United States,residing at Midland Park, in the county of Bergen and State of l ewJersey, have invented certain new and useful Improvements in Packings;and I do hereby declare the following to be a full, clear, and exactdescription of invention, such as will enable others skilled in the artto which it appertains to make and use the same.

This invention relates to packings, and has for an object to provide apacking emnew and improved features of strength, elasticity and wearingqualities.

further object of the invention is to reinforce. each provided with alive rubber core.

With these and other objects in view the invention consists in certainnovel features of construction, combination and arrangement of parts aswill be hereinafter more fully described and claimed.

Fig. 3 is aperspective view of the metal reinforce. Fig. 4 is an enlargedtransverse sectional view through one of the rolls.

Like characters of reference designate corresponding parts throughoutthe several views.

The improved packing which forms the subject-matter of this applicationcomprises a metal reinforce 10 formed in the general construction of anI-beam, having cut-out portions 11 which permit the reinforce to beSpecification of Letters Patent. Application filed September 2, 1916.Serial No.

curved to correspond to the required curvature of the packing as shownparticularly at Fig. 1. Two rolls of material are made as shown in theenlarged view at Fig. 4, comprising each a live rubber core 12 withrubberized fabric rolled around such core in the usual well-known mannerfor vulcanizing purposes. The two rolls are placed upon opposite sidesof the reinforce 10 intermediate its two flanges. A plurality of stripsof rubberized. fabric 13 and 14 are now placed on the outer periphery ofthe associated rolls and reinforce, and a final outer fabric 15 placedupon the periphery of the two fabrics 13 and 14 and brought down alongthe sides of the rolls. The entire structure is now by some approvedmeans pressed and molded into the form shown at Fig. 2, in cross sectionsubstantially rectanwith the inner periphery of the metal gular,reinforce flush with the inner surface of the The entire structure 1scompleted packing. now Vulcanized in the usual well-known manner, andthe packing is complete.

I claim 1. In a packing, a metal reinforce, rolls located upon oppositesides of the reinforce, and each comprising a rubber core and fabriclaminations, and fabrics spanning over and joining the rolls together.

2. A packing comprising a metal reinforce of substantially I-beam formhaving cut-out portions upon one side forming the inner surface of thepacking, rolls located upon opposite sides of the metal reinforcec0mrubber cores and laminations of ning the cores, canized connectingthe rolls through the cutout portions of the metal reinforce.

In testimony whereof I affix my signature.
